l This invention relates tonsinkers for'v fishing lines. andmoreparticularlyto a ysinker which also "serves-as' an anchor to hold theend ofy the line attached thereto in place when the line is being usedrough or rapidlymovingwater, asin surf fishing.

It is among the objects of the invention to provide an improved fishingline sinker which can be secured to a shing line for use as a Weight incasting; which has a flat face and blade formations extending along theedges of the flat face and adapted to dig into loose sand along a shoreor beach so that the sinker functions as an anchor to hold an associatediishingline in place against the action of rough or rapidlymoving water,as in surf iishing; which is firmly engaged in the sand by the pull ofthe associated shing line thereon; which can be made in various weightsfor use with fishing equipment Vof varying strengths and sizes; andwhich is simple and durable in construction, economical to manufacture,positive and effective in operation, and neat and attractive inappearance.

Other objects and advantages will become apparent from a considerationof the following description and the appended claims in conjunction withthe accompanying drawing, wherein:

Figure 1 is a perspective View of a fishing line sinker illustrative ofthe invention;

Figure 2 is a topplan view of the sinker illustrated in Figure 1;

Figure 3 is a side elevational view of the sinker; and

Figure 4 is a somewhat diagrammatic side elevational view of the sinkershown in operative position with a fishing line attached thereto.

With continued reference to the drawing, the sinker comprises a body ofheavy, non-buoyant material, such as lead, of flattened, substantiallytriangular shape having a base end Il! and side surfaces II and I2extending in the same direction one from each end of the base end orsurface IIl of the body and converging symmetrically in a direction awayfrom Ythe base. The sides II and I2 of the body preferably have a slightreverse or ogee -curvature so that the portions thereof adjacent theends of the base I are concavely curved and the portions thereofadjacent the end of the body remote from the base are convexly curvedand the end of the body remote A from the base is convexly rounded.

The body tapers in thickness in a direction away from the base end IIJthereof and has two faces I3 and I4 which are concavely curved adjacentthe base end-or surface II) of the body for a purpose to be laterdescribed in detail.

,The base'end surface I Ilof the body is of elongated, rectangularcross' sectional shape having straight and substantially parallelside.edges|5 and I6 and is transversely concave, preferably beingprovided immediateits width with asl'iallow groove I'I disposedsymmetrically of the width of the base end surface I0 and having datareas I8 and I9 disposed between the edegs I5 and I6 respectively andthe respectively adjacent sides of the groove I1, the areas I8 and I9being disposed substantially in a common plane, as illustrated in Figure3.

The flat areas IB and I9 extend outwardly from the corresponding edgesof the groove I1 to the side edges I5and I6 of the base end II) of thebody and the faces I3 and I4 of the body extend from theside edges I5and IB respectively to the apical end of the substantially triangularbody. The concave curvature of the faces I3 and I4 adjacent the sideedges I5 and I6 provides a construction wherein the portions of the bodyadjacent the side edges I5 and I6 project substantially laterallyoutward to provide blade formations 20 and 2| which taper in thicknessacross the thickness of the body from the face surfaces I3 and I4 to anacute condition along the side edges I5 and I6 of the base end of thebody.

A line attaching eye 22 is secured in the body and projects from thebody substantially at the center of the surface of the base end Ill ofthe body.

The length of the base end of the body is preferably substantially asgreat as the width of the body from the base end I0 to the apical end 23thereof and the width of the base end I0 is materially less than thelength of the base end, preferably being less than one-half the lengthof the base end so that the body will not roll when lying on the sandand subjected to the action of moving water.

In the use of the sinker, the sinker is attached by means of the lineattaching eye 22 vto one end of a fishing line, as indicated at 24 inFigure 4, and iscast by a suitable casting rod, such as a surf castingrod. After the sinker has been cast out into the Water, the line 24 isreeled in suiiciently to move the sinker so that the base end I IJthereof faces the rod from which the line extends and so that the lowerblade formationl of the sinker digs into the sand on which the sinkerrests, as illustrated in Figure 4. Upon further scope of the inventionbeing indicatedfgbythe,

appended claim rather than by the foregoing description, and all changesWhichcomeyvithin lthe meaning and range of equivalency ofjthe claim are,therefore, intendedto be embraced therein.

What is claimedis: Ashing line sinker comprising a body of sub- Ystant-iallytriangular shape having a Vbase end which; is of elongatedrectangular shape with a shallow groove extending longitudinally andsymn metrically-of Vthe width thereof and fiat areas disposed betweenthe opposite edges of said groove and the corresponding side edges ofsaid base, said body having top and bottom faces which are concavelycurved in a direction away from the corresponding side edges of saidbase end so that the portions of said body adjacent said side edgesproject substantially laterally from the remainder of the body andconstitute blade Aformations taperingj in thickness transversely of Athethicknessof said body toan acute condition along the corresponding sideedges of :said base end, and a line attaching eye projecting from saidbody substantially at the center of the f base end thereof.
